This is not a big deal, but I don't understand how this is working and I'd prefer to bend my mind around it.
I have not figured out yet how WP-Cache *handles* expired pages. I have expiration set at the default 3600 seconds, and I'll check my cache via WP-Cache Options - it will show the expired files in red.
I guess I was surprised to see them in there and thought they would just be replaced by the new cache (every 3600 seconds). Am I right to think that these will remain in there (cached) until I delete them? I guess the thought is that if I haven't changed the files then why would I ever need to delete the cached files. Is that right?
The other thing I don't get is why I have duplicate cached items. For example, one is 903 seconds old and the exact same page has a duplicate that is 910 seconds old. Why the dup?
Everything is working fine, I just would like to understand it more if anyone cares to elaborate.
